Taking canned beverage as an example, directly putting canned beverage in putting thing container 110, putting thing container 110 can set up the cavity that can hold canned beverage, circulation circuit 140 passes through the outside of cavity, and cold-storage liquid flows through can hugging closely the lateral wall flow of cavity when putting thing container 110 like this for cold-storage liquid can carry out the heat transfer with canned beverage.

Referring to fig. 1, it should be noted that in the present embodiment, the storage container 110 is disposed in the refrigerating chamber 210 of the refrigerator 200, and the liquid storage container 120 is disposed near the evaporator 230 or directly contacts the evaporator 230, it can be understood that the evaporator 230 has a lower temperature and can provide sufficient cooling capacity, so that the cooling medium can be cooled to a lower temperature, and the quick cooling effect is better. The adopted cold accumulation liquid is an ethanol solution with the concentration of 40-60%, the cold accumulation liquid can accumulate the obtained refrigerating capacity in a freezing energy mode, the adopted pump 130 is a water pump capable of conveying the cold accumulation liquid, the cold accumulation liquid exchanges heat with the canned beverage when flowing through the storage container 110, and the stored freezing energy is released during heat exchange to cool the canned beverage.

It can be understood that the liquid storage container 120 has a sufficient capacity to store the cold storage liquid, so that the delivered cold storage liquid stores the refrigeration energy to cool the food to the desired temperature, and of course, the capacity of the liquid storage container 120 can be set according to different quick cooling requirements, and the larger the capacity, the more the stored refrigeration energy, the higher the quick cooling efficiency. The storage container 110 is provided with a cooling channel for the flow of the cold accumulation liquid, and the cooling channel can be provided with a cavity for containing the canned beverage, so that the cold accumulation liquid releases freezing energy to cool the beverage when flowing through the cooling channel.

When the rapid cooling mode is turned on, the refrigerator 200 forces the compressor to operate at a high speed or at a normal speed for cooling, which may be understood as that, in the normal operation process of the refrigerator 200, in order to keep food in a constant low-temperature cold state, the operation of the cooling system is usually changed according to temperature control, for example, after the temperature of the refrigerating chamber 210 reaches a set temperature, the compressor stops cooling or operates at a lower power, and after a period of time, normal cooling is resumed, and the cycle is repeated, so as to achieve the effect of adjusting the temperature of the refrigerating chamber 210.

In the embodiment, the user can display the options of the reserved time and the preset temperature through the display panel on the refrigerator 200, and the user can set the reserved time or the adjustment of the cooling temperature of the beverage through the display panel, so that the use is flexible and convenient, and the higher drinking experience is achieved. For example, when the user quickly cools the canned beverage at the scheduled time, the canned beverage is placed in the storage container 110, the scheduled time is set, and when the scheduled time is not reached, the refrigerator 200 operates according to the current operating parameters, and the quick cooling apparatus 100 does not operate. When the reservation time is reached, the quick-freezing mode is started, the starting pump 130 is controlled to convey the cold accumulation liquid to the storage container 110, the cold accumulation liquid is utilized to transfer the cold amount of the evaporator 230, sufficient cold amount can be provided, the cold accumulation liquid in the low-temperature state exchanges heat with canned beverages when passing through the storage container 110, the cold accumulation liquid can take away the heat of the beverages, and the beverages are cooled rapidly, so that the purpose of rapid cooling is achieved, the cooling effect is obvious, reservation rapid cooling can be realized, the use is more flexible, the frozen beverages can be drunk when the reservation time is reached, and the use experience is better.

The preset time can be set by inputting a preset quick-cooling mode starting instruction, for example, when a quick-cooling beverage starts after 30min (minutes), the beverage is put into the storage container 110, then the preset time is input, the preset quick-cooling mode is started, the quick-cooling mode is automatically started after 30min, the preset quick-cooling mode starting instruction can be input through manual input, voice input, remote control input or other modes, and the input mode of the preset quick-cooling mode instruction is not further limited by the embodiment of the invention.

Referring to fig. 1, the storage container 110, the liquid storage container 120 and the pump 130 are sequentially connected to form a circulation loop 140, and the formed circulation loop 140 is a closed channel. Specifically, stock solution container 120 is connected to the input of pump 130, and the output of pump 130 is connected and is put the input of cooling channel in the thing container 110, and wherein, stock solution container 120 is provided with liquid outlet and inlet, and the liquid outlet is connected with pump 130, and the inlet passes through duct connections cooling channel's output, and cold-storage liquid circulation process is: pump 130 pumps and carry to putting thing container 110 with cold-storage liquid from the liquid outlet of stock solution container 120, cold-storage liquid flows back to stock solution container 120 after the heat transfer at the cooling channel who puts thing container 110, so circulation, until pump 130 stop work, the cycle process is driven by pump 130 power, can continuously provide cold-storage liquid like this and carry out the heat transfer with the beverage, guarantee that sufficient refrigerating capacity makes the beverage obtain the cooling, realize quick cooling, the cooling effect is better.

In some embodiments, the output power of the pump 130 is adjustable, for example, an axial flow pump, the axial flow pump drives the liquid to flow by the thrust generated by the high-speed rotation of the impeller, and the higher the rotation speed of the impeller is, the faster the cold storage liquid flows, so that the rotation speed is adjusted by the output power, and the flow speed of the cold storage liquid can be adjusted. It will be readily appreciated that the faster the cold storage fluid flows, the more efficient the cooling efficiency, and the more efficient rapid cooling can be achieved by controlling the pump 130 to operate at the highest rotational speed.

Referring to fig. 1, a single-system double-door refrigerator 200 is taken as an example, the refrigerator 200 includes a refrigerating chamber 210 and a freezing chamber 220, the refrigerating chamber 210 is located above the freezing chamber 220, the refrigeration system includes a compressor, an evaporator 230, a condenser and a capillary tube, a refrigeration cycle of the refrigerator 200 mainly includes four processes, namely, compression, condensation, throttling and evaporation, the compressor compresses a refrigerant, the capillary tube throttles high-pressure and medium-temperature refrigerant liquid sent by the condenser into low-pressure and low-temperature refrigerant liquid, the throttled refrigerant flows through the evaporator 230 to generate refrigeration capacity, and the refrigeration capacity is sent to the refrigerating chamber 210 and the freezing chamber 220, so that heat is absorbed, and the purposes of refrigeration and temperature reduction are achieved.

As shown in fig. 1, in the embodiment, the storage container 110 is disposed in the refrigerating compartment 210, so that the storage container 110 is in a low-temperature environment, heat exchange between the beverage and the environment is reduced, and the quick cooling efficiency is improved. The liquid storage container 120 is arranged to contact the evaporator 230, so that the cold storage liquid in the liquid storage container 120 can fully obtain cold energy, and the cold storage liquid can be cooled more rapidly.

As shown in fig. 1, in the case of the air-cooling type refrigerator 200, the evaporator 230 is installed at a position separated from the refrigerating chamber 210 and the freezing chamber 220, and cold air generated by the evaporator 230 is supplied to the refrigerating chamber 210 and the freezing chamber 220 by the fan 260, thereby cooling the refrigerating chamber 210 and the freezing chamber 220. Therefore, the evaporator 230 has a separate installation area 240, the installation area 240 having a lower temperature with respect to the refrigerating chamber 210 and the freezing chamber 220, enabling the cold storage liquid to take a large amount of cold in a short time. In this embodiment, the liquid storage container 120 is a liquid storage tank, and the liquid storage tank is installed in contact with the evaporator 230, so as to ensure that the cold storage liquid is rapidly cooled and stores sufficient cold, and the liquid storage container has an efficient rapid cooling effect.

When the quick cooling mode is operated, the controller is used for controlling the pump 130 to convey the cold accumulation liquid to the storage container 110 along the circulation loop 140 so as to exchange heat between the cold accumulation liquid and food to be quickly cooled, and meanwhile, the controller controls to reduce or close the cold supply to the refrigerating chamber 210 and/or the freezing chamber 220, so that the cold supply of the evaporator can be concentrated to the cold supply of the storage container 120, the cooling efficiency is effectively improved, and the purpose of quick cooling is achieved.

In some embodiments, when the pump 130 is activated, the supply of cold to the refrigerating chamber 210 and the freezing chamber 220 can be reduced, specifically, the refrigerator 200 can supply cold to the refrigerating chamber 210 and the freezing chamber 220 through the fan 260, the fan 260 is a fan of a refrigerating system of the refrigerator 200, the air supply amount can be reduced by reducing the rotation speed of the fan 260, so as to meet the requirement of cold of the centralized evaporator 230, and it can be understood that the refrigerating chamber 210 and the freezing chamber 220 can be supplied with cold by one fan 260 or by independent fans 260. In some particular embodiments, the refrigerated compartment 210 is provided with a damper 250, and a high concentration of cold can be achieved by closing the damper 250.

In some embodiments, the supply of cold to the refrigerating chamber 210 and the freezing chamber 220 may be turned off when the pump 130 is activated, thus maximizing the concentration of cold from the evaporator 230, and in embodiments, the cooling of the refrigerating chamber 210 and the freezing chamber 220 is turned off by turning off the fan 260 in case of supplying cold air to the refrigerating chamber 210 and the freezing chamber 220 by the fan 260.

As shown in FIG. 1, in some particular embodiments, the refrigerated compartment 210 is provided with a damper 250, and the damper 250 is closed at the same time that the fan 260 is closed. In some embodiments, a damper 250 may be provided in the freezer compartment 220, and the damper 250 may be closed for both the refrigerator compartment 210 and the freezer compartment 220 while the fan 260 is turned off. Like this, the refrigerating output that makes evaporimeter 230 in the short time can obtain highly concentrating, makes cold-storage liquid can rapid cooling, and evaporimeter 230 can provide sufficient refrigerating output, and the rapid cooling is efficient higher, and the effect is better.

In some embodiments, a temperature sensor for detecting the temperature of food to be rapidly cooled is provided on the storage container 110, and in a rapid cooling mode of a preset temperature, when the temperature of the food reaches the preset temperature, the controller controls to turn off the pump 130 and to resume cooling the refrigerating compartment 210 and the freezing compartment 220. Here, the recovery of cooling the refrigerating compartment 210 and the freezing compartment 220 may be understood as recovering the state where cooling of the refrigerating compartment 210 and the freezing compartment 220 is reduced or turned off to the original operation state, and exiting the rapid cooling mode.

When the temperature of the food to be rapidly cooled does not reach the preset temperature, the pump 130 is kept in the on state, and the cooling states of the refrigerating chamber 210 and the freezing chamber 220 in the rapid cooling mode are maintained; when the temperature of the food to be rapidly cooled reaches a preset temperature, the pump 130 is turned off, and the cooling of the refrigerating chamber 210 and the freezing chamber 220 is resumed, the rapid cooling mode is exited, and the refrigerator 200 resumes its normal operation. For example: the preset temperature of the canned beverage is set to be 5 ℃, when the preset time is reached, the canned beverage enters a quick cooling mode, the pump 130 is started to operate, the air door 250 and the fan 260 are closed, the temperature of the beverage is detected in real time in the quick cooling process to reach the preset temperature, the quick cooling state is kept when the temperature of the beverage does not reach the preset temperature, when the preset temperature is reached, the pump 130 is closed, the air door 250 and the fan 260 are simultaneously opened, and the canned beverage exits the quick cooling mode. Of course, the preset temperature is not limited to the temperature shown in the embodiment, and the preset temperature can be set to a temperature range of 0 ℃ to 10 ℃. The preset temperature is the optimal taste temperature of the food and is set according to the food type, for example, the drinking taste of the beverage is optimal in the temperature range of 3-6 ℃, and the eating taste of the fruits such as watermelon, pawpaw and the like is optimal at about 8 ℃. In some embodiments, the compressor of the refrigerator 200 is started to perform refrigeration, if the refrigerator 200 is the fixed-frequency refrigerator 200, the compressor operates at a normal rotation speed, the rotation speed of the compressor is fixed and unchanged in the operation process of the fixed-frequency refrigerator 200, and the normal rotation speed is the fixed operation rotation speed of the compressor; if the refrigerator 200 is the inverter refrigerator 200, the compressor operates at the highest rotation speed, and the maximum cooling capacity can be generated, so that the operation at the maximum cooling capacity can be ensured no matter the inverter refrigerator 200 or the fixed-frequency refrigerator 200 is adopted, sufficient cooling capacity supply is provided, and efficient quick cooling is realized.

Considering that the compressor may be in a standby state before the pump 130 is operated, that is, the refrigerator 200 stops cooling, or the refrigerator 200 is just turned on and needs to be operated for a certain period of time when the cooling capacity is insufficient, the compressor is started to operate for cooling before the pump 130 is started. To further ensure sufficient cooling capacity, the compressor may be set to operate after a certain interval time and then the pump 130 may be started, for example, the refrigerator 200 is an inverter refrigerator 200, when the rapid cooling mode is started, the compressor operates at the highest rotation speed, and after 30 seconds, the pump 130 is started to ensure that the cold storage liquid is cooled and has a relatively low temperature.

In some embodiments, before starting the rapid cooling apparatus 100, it is necessary to determine whether the current operating state of the refrigerator 200 is suitable for starting the rapid cooling mode. Specifically, the operating state of the refrigerator 200 may be determined by obtaining the current operating parameter of the refrigerator 200, where the current operating parameter may include a set temperature, a rotational speed of the fan 260, a rotational speed of the compressor, and the like, and considering that in the defrosting operation state of the refrigerator 200, the compressor is not operated, the evaporator 230 has a high temperature, and cannot provide a cooling capacity for rapid cooling, and the refrigerator 200 starts defrosting to a priority level based on protection of the basic performance of the refrigerator 200. Therefore, if the current working state of the refrigerator 200 is the defrosting operation state, the pump 130 needs to be started for quick cooling after the defrosting operation is finished and the compression operation needs to be performed for a set time, so that the problem that the refrigerating capacity is insufficient due to the high temperature of the evaporator 230 in the defrosting process and the quick cooling effect is affected is avoided. It can be understood that, after the defrosting operation is finished, since the evaporator 230 has a higher temperature, the cooling capacity is lower, and the effect of opening the quick cooling is not good, and therefore, the compressor needs to operate for the set time, for example, the set time may be 30min, and certainly, the compressor is not limited to the time length shown in the embodiment.

Referring to fig. 2 to 6, a control method of a rapid cooling device according to a second aspect of the present invention is suitable for controlling the rapid cooling device 100 shown in fig. 1, and the control method of the rapid cooling device in this embodiment may be executed by the control device 300 of the refrigerator 200 in this embodiment of the present invention.

The structure of the rapid cooling device 100 shown in fig. 1 is described in the above embodiments, and is not described herein again. Referring to fig. 2, the control method of the instant cooling device includes, but is not limited to, the following steps:

step S100: setting a reservation time;

step S200: when the appointed time is reached, controlling to start a quick cooling mode;

step S300: when the rapid cooling mode is operated, the pump 130 is controlled to operate to deliver the cold storage liquid to the storage container, and to reduce or shut off the supply of cold to the refrigerating compartment 210 and/or the freezing compartment 220.

Taking canned beverage as an example for explanation, when the canned beverage needs to be reserved and rapidly cooled, the canned beverage is put into the storage container 110, the reserved time is set, and when the reserved time is not reached, the refrigerator 200 operates according to the current operating parameters, the rapid cooling device 100 does not operate, and the refrigerator 200 operates normally. When the reservation time is reached, the quick-freezing mode is started, the cold accumulation liquid is conveyed to the storage container 110 through the pump 130, the refrigeration capacity of the refrigerator 200 is transferred by the cold accumulation liquid, so that the refrigeration capacity can be more concentrated, the cold accumulation liquid in a low-temperature state exchanges heat with canned beverages when passing through the storage container 110, the heat of the canned beverages can be taken away by the cold accumulation liquid, and the beverages to be canned are rapidly cooled, so that the purpose of rapid cooling is achieved, the cooling effect is remarkable, the reservation rapid cooling can be realized, and a long-time cooling process is not required.

In this embodiment, the storage container 110, the liquid storage container 120 and the pump 130 are connected to form a circulation loop 140 for circulating the cold storage liquid. When pump 130 starts, the cold accumulation liquid in stock solution container 120 is pumped out, and carry to putting thing container 110 along circulation loop 140, cold accumulation liquid carries out the heat exchange through putting thing container 110 and canned beverage, thereby take away the heat of beverage, the cold accumulation liquid through the heat transfer flows back to stock solution container 120 along circulation loop 140, cold accumulation liquid obtains cooling again in stock solution container 120, so circulation, until pump 130 stop work, can continuously provide cold accumulation liquid and canned beverage and carry out the heat transfer like this, guarantee that sufficient refrigerating capacity makes canned beverage obtain the cooling, realize quick cooling, the cooling effect is better.

In some embodiments, the higher the output power of the pump 130, the greater the driving force, and the greater the flow rate of the cold storage liquid, so that adjustment of the flow rate of the cold storage liquid can be achieved by adjusting the output power of the pump 130, and the faster the cold storage liquid flows, the higher the cooling efficiency, and thus, more efficient rapid cooling can be achieved. In this embodiment, the pump 130 is operated at the highest output power, so that the flow rate of the cold storage liquid can be the highest, and a better quick cooling effect can be obtained.

Step S100: setting a reservation time;

step S200: when the preset time is reached, controlling to start a quick cooling mode;

step S310: when the rapid cooling mode is operated, the pump 130 is controlled to operate at the highest rotation speed, the cold storage liquid is delivered to the storage container 110 to exchange heat with the canned beverage, and the supply of cold to the refrigerating chamber 210 and/or the freezing chamber 220 is controlled to be reduced or closed.

Referring to fig. 3, in some embodiments, a control method of a rapid cooling device includes the steps of:

step S110: setting a preset temperature;

step S210: starting a quick cooling mode;

step S300: when the rapid cooling mode is operated, the pump 130 is controlled to operate to convey the cold storage liquid to the storage container 110, and the cooling of the refrigerating chamber 210 and/or the freezing chamber 220 is controlled to be reduced or closed;

step S400: when the temperature of the canned beverage reaches the preset temperature, the control turns off the pump 130 and restores the cooling of the refrigerating compartment 210 and/or the freezing compartment 220.

It should be noted that, in the refrigeration state of the refrigerator 200, the compressor operates, the generated refrigeration capacity is output from the evaporator 230, and the liquid storage container 120 is disposed close to or directly contacts the evaporator 230, so that the cold storage liquid in the liquid storage container 120 can fully obtain the refrigeration capacity, and the cold storage liquid is cooled more rapidly. Because the refrigerating process of the refrigerator 200 can deliver cold energy to the refrigerating chamber 210 and the freezing chamber 220, when the pump 130 is started, the cold energy is supplied to the refrigerating chamber 210 and the freezing chamber 220 by reducing or closing, so that the cold energy of the evaporator 230 can be more concentrated, the cold storage liquid can be rapidly cooled, sufficient cold energy can be provided, and the rapid cooling efficiency can be effectively improved.

Whether the temperature of the beverage reaches the preset temperature or not is detected in real time through the temperature sensor in the running process of the quick cooling mode, and the beverage is kept in a quick cooling state when the temperature of the beverage does not reach the preset temperature. When the temperature of the food to be rapidly cooled reaches a preset temperature, the pump 130 is turned off, and the cooling of the refrigerating chamber 210 and the freezing chamber 220 is resumed, the rapid cooling mode is exited, and the refrigerator 200 resumes its normal operation. For example: the preset temperature of the beverage is set to be 5 ℃, when the preset time is reached, the rapid cooling mode is entered, the pump 130 is started to operate, the air door 250 and the fan 260 are closed, and the settable temperature range of the preset temperature can be 0 ℃ to 10 ℃. The preset temperature is the optimal taste temperature of the food and is set according to the type of the food.

In some embodiments, reducing cooling of the refrigerator compartment 210 and the freezer compartment 220 includes reducing the rotational speed of the refrigerator compartment 210 and the fan 260 to reduce the amount of air supplied. Thus, a specific example of step S300 in the embodiment shown in fig. 3 is provided, which includes:

step S320: when the rapid cooling mode is operated, the pump 130 is controlled to operate and the rotational speeds of the refrigerating compartment 210 and the fan 260 are reduced to reduce the amount of supplied air.

In this embodiment, the refrigerator 200 supplies cool air to the refrigerating chamber 210 and the freezing chamber 220 by the blower fan 260, and the amount of the supplied air can be reduced by reducing the rotational speed of the blower fan 260. It is understood that the refrigerating compartment 210 and the freezing compartment 220 may be supplied with cool air by one fan 260 or by separate fans 260. It is easily understood that turning off the cooling of the refrigerating compartment 210 and the freezing compartment 220 may be accomplished by turning off the fan 260, and thus, turning off the cooling of the refrigerating compartment 210 and the freezing compartment 220 includes turning off the refrigerating compartment 210 and the fan 260. A specific example of step S300 in the embodiment shown in fig. 3 is provided, which includes:

step S330: when the fast cooling mode is operated, the pump 130 is controlled to operate and the refrigerating compartment 210 and the fan 260 are turned off.

In another embodiment, the refrigerating chamber 210 is provided with a damper 250, the freezing chamber 220 supplies cold by sending cold air through the fan 260, the cold supply of the refrigerating chamber 210 can be closed by closing the damper 250, and the fan 260 is closed, thereby achieving the purpose of reducing the consumption of refrigerating capacity. Thus, a specific example of step S300 in the embodiment shown in fig. 3 is provided, which includes:

step S340: when the rapid cooling mode is operated, the pump 130 is controlled to operate and the blower 260 is turned off and the damper 250 is closed.

Like this, the refrigerating output that makes evaporimeter 230 in the short time can obtain highly concentrating, makes cold-storage liquid can rapid cooling, and evaporimeter 230 can provide sufficient refrigerating output, and the rapid cooling is efficient higher, and the effect is better.

Referring to fig. 4, in some embodiments, a control method of a rapid cooling device includes the steps of:

step S120: setting a reservation time and a preset temperature;

step S340: when the rapid cooling mode is operated, the pump 130 is controlled to operate, and the fan 260 and the damper 250 are closed;

step S410: when the temperature of the canned beverage reaches the preset temperature, the control turns off the pump 130 and turns on the fan 260 and the damper 250, and the quick cooling mode is exited.

Specifically, a specific example of step S410 in the embodiment shown in fig. 4 is provided, and step S411: when the temperature of the canned beverage cools to 5 ℃, the pump 130 is turned off and the fan 260 and damper 250 are turned on, exiting the rapid cooling mode.

When the preset time is reached, the quick cooling mode is entered, the pump 130 is started to operate, the air door 250 and the fan 260 are closed, when the beverage is cooled to 5 ℃, the pump 130 is closed, and the air door 250 and the fan 260 are simultaneously opened to exit the quick cooling mode. Of course, the preset temperature is not limited to the temperature shown in the embodiment, for example, the preset temperature may be set to 2 ℃, 10 ℃ or the like. After the rapid cooling mode exits, the rapid cooling device 100 stops operating, and the refrigerator 200 resumes the operating state before rapid cooling and continues operating. This avoids the cooling temperature of the canned beverage being too high or too low and degrading the drinking experience.

In some embodiments, in consideration that the compressor may be in a standby state before the pump 130 operates, that is, the refrigerator 200 stops cooling, the compressor is started to operate for cooling before the pump 130 is started, and in order to further ensure that the sufficient cooling capacity is provided, the pump 130 may be started after the compressor is operated for a certain period of time. If the refrigerator 200 is the fixed-frequency refrigerator 200, the compressor operates at a normal rotating speed, the rotating speed of the compressor is fixed and unchanged in the operation process of the fixed-frequency refrigerator 200, and the normal rotating speed is the fixed operating rotating speed of the compressor; if the refrigerator 200 is the inverter refrigerator 200, the compressor is operated at the highest rotation speed, and efficient rapid cooling is realized.

In some embodiments, the control node that ends the rapid cooling mode may provide a specific example of step S400 in the embodiment shown in fig. 3 for the pump 130 to run for a preset time, including:

step S420: when the running time of the pump 130 reaches the preset time, the control turns off the pump 130, turns on the fan 260 and the damper 250, and exits the quick cooling mode.

The preset time is set to different time lengths according to different foods, when the pump 130 runs for the preset time, the pump 130 is turned off, the cold storage liquid is stopped being conveyed to the storage container 110, the cold supply to the refrigerating chamber 210 and the freezing chamber 220 is also resumed, namely, the foods are stopped being continuously cooled, and the refrigerator 200 resumes normal operation. The predetermined time range may be 5min to 30 min. In this embodiment, taking the preset time as 15min as an example, the step 421 specifically includes: and after the running time of the pump 130 reaches 15min, controlling to close the pump 130 and open the fan 260 and the damper 250, and exiting the quick cooling mode.

When entering the rapid cooling mode, the pump 130 is started to operate, the air door 250 and the fan 260 are closed, after the operation is carried out for 15min, the pump 130 is closed, and the air door 250 and the fan 260 are simultaneously opened to exit the rapid cooling mode. Of course, the preset time is not limited to the time length shown in the embodiment, such as the preset time is set to be 8min, 12min or 20 min. Therefore, the quick cooling mode is controlled to be closed according to the preset time, so that on one hand, the food is prevented from being frozen due to long-time freezing, on the other hand, the temperature of the refrigerating chamber 210 and the freezing chamber 220 is prevented from deviating from the normal temperature range due to insufficient cold capacity for a long time, the refrigerating chamber 210 and the freezing chamber 220 can be kept in a sufficiently low temperature state, and the normal use of the refrigerator 200 is ensured.

In some embodiments, the control node for the end of the rapid cooling mode is that the temperature of the refrigerating compartment 210 or the freezing compartment 220 exceeds a set temperature, it is understood that the temperature of the refrigerating compartment 210 and the freezing compartment 220 is maintained within a normal operating temperature range in a normal operation state of the refrigerator 200, and the temperature of the refrigerating compartment 210 and the freezing compartment 220 is monitored in real time by using temperature sensors. In the operation process of the quick cooling mode, in order to ensure the basic performance of the refrigerator 200, the quick cooling mode is stopped when the temperature of the refrigerating chamber 210 or the freezing chamber 220 is detected to exceed the set temperature, the refrigerating chamber 210 and the freezing chamber 220 are restored to be cooled, and the influence of insufficient cooling capacity on the fresh-keeping of other food materials in the refrigerating chamber 210 and the freezing chamber 220 is avoided. For example, the normal operation temperature of the refrigerating compartment 210 is between 4 ℃ and 8 ℃, the rapid cooling mode is stopped when it is detected that the temperature of the refrigerating compartment 210 exceeds the set temperature, and the cooling of the refrigerating compartment 210 and the freezing compartment 220 is resumed, in the embodiment, the set temperature of the refrigerating compartment 210 is set to 15 ℃, and a specific example of step S400 in the embodiment shown in fig. 3 is provided, which includes:

step S430: when the temperature of the refrigerating chamber 210 exceeds 15 ℃, the control turns off the pump 130 and turns on the fan 260 and the damper 250, and the quick cooling mode is exited.

As another example, the normal operation temperature of the freezing compartment 220 is about-18 ℃, and in the embodiment, the set temperature of the freezing compartment 220 is set to 0 ℃, that is, when the temperature of the freezing compartment 220 exceeds 0 ℃, the pump 130 is controlled to be turned off, the fan 260 and the damper 250 are controlled to be turned on, and the rapid cooling mode is exited.

In some embodiments, the control node for ending the rapid cooling mode is that the temperature of the refrigerating chamber 210 or the freezing chamber 220 deviates from the normal operating temperature range for more than a set time period, which may be understood as that the temperature of the refrigerating chamber 210 and the freezing chamber 220 is maintained within the normal operating temperature range in the normal operating state of the refrigerator 200, and in the rapid cooling mode, the temperature of the refrigerating chamber 210 and the freezing chamber 220 deviates from the normal operating temperature, and if the operating time for the temperature of the refrigerating chamber 210 and the freezing chamber 220 deviates from the normal operating temperature for too long time, the temperature may be increased to affect the preservation of other food materials. For example, the normal operation temperature range of the refrigerating chamber 210 is between 4 ℃ and 8 ℃, and when the refrigerating chamber 210 deviates from the normal temperature range for more than 40min, the control switches off the pump 130 and switches on the fan 260 and the damper 250 to exit the quick cooling mode. For another example, the normal operation temperature range of the freezing chamber 220 is between-24 ℃ and-4 ℃, and when the freezing chamber 220 deviates from the normal temperature range for more than 30min, the pump 130 is controlled to be closed, the fan 260 and the damper 250 are controlled to be opened, and the quick cooling mode is exited. Therefore, the phenomenon that the temperature of the refrigerating chamber 210 and the freezing chamber 220 deviates from the normal operation temperature range for a long time due to insufficient cold quantity can be avoided, and the freshness of other food materials is guaranteed.

In the embodiment, after the rapid cooling mode exits, the rapid cooling apparatus 100 stops operating, and the refrigerator 200 returns to the operating state before rapid cooling and continues to operate.

Referring to fig. 5, in some embodiments, considering that the compressor may be in a shutdown state before the pump 130 is operated, that is, the refrigerator 200 is in a pause cooling state, when the rapid cooling mode is started, the control method further includes the steps of:

step S210: receiving a rapid cooling mode starting instruction, and judging the working state of the compressor of the refrigerator 200;

step S220: if the compressor works normally, the quick cooling mode is directly started; if the compressor stops working, it is determined whether the refrigerator 200 is in a defrosting state.

Step S230: if the refrigerator 200 is in a defrosting state, starting the compressor after the defrosting is finished, and starting a quick cooling mode after the compressor runs for the first time; if the refrigerator 200 is not in the defrosting state, the compressor is directly started, and the rapid cooling mode is started after the compressor is operated for the second time.

Considering that the compressor is not operated even in the defrosting operation state of the refrigerator 200, and the evaporator 230 is at a high temperature and cannot provide cooling capacity for rapid cooling, the refrigerator 200 starts defrosting to a priority level based on protection of basic performance of the refrigerator 200. Therefore, when the operating state of the compressor is determined to be the shutdown state, it is necessary to determine whether the refrigerator 200 is in the defrosting state.

It can be understood that if the current working state of the refrigerator 200 is the defrosting operation state, the pump 130 needs to be started for quick cooling after the defrosting operation is finished and the compression needs to be performed for a set time, so as to avoid that the refrigerating capacity is insufficient due to a high temperature of the evaporator 230 during the defrosting process, and the quick cooling effect is affected. After the defrosting operation is finished, the compressor needs to operate for the first time, and then the quick cooling mode is started, which can be understood that after the defrosting operation is finished, because the temperature of the evaporator 230 is also higher, the cooling capacity is less at the moment, and the effect of starting the quick cooling mode is not good. If the refrigerator 200 is not in the defrosting state, the evaporator 230 has less cooling capacity when the compressor is just started, and therefore, the quick cooling mode needs to be started after the compressor runs for a second time, the first time can be set within a range of 20min to 40min, and it can be understood that the duration of the second time is less than that of the first time, and the second time can be set within a range of 30s to 60 s.

In this embodiment, the first time is set to 30min, and the second time is set to 30S, specifically, specific examples of steps S210 to S230 in the above embodiments are provided, including but not limited to the following steps:

step S220: if the compressor works normally, the quick cooling mode is directly started; if the compressor stops working, judging whether the refrigerator 200 is in a defrosting state;

step S231: if the refrigerator 200 is in a defrosting state, starting the compressor after the defrosting is finished, and starting a quick cooling mode after the compressor runs for 30 min; if the refrigerator 200 is not in the defrosting state, the compressor is directly started, and the quick cooling mode is turned on after the compressor is operated for 30 s.

If the refrigerator 200 is a fixed-frequency refrigerator, the compressor operates at a normal rotating speed, the rotating speed of the compressor is fixed in the operation process of the fixed-frequency refrigerator 200, and the normal rotating speed is the fixed operating rotating speed of the compressor; if the refrigerator 200 is a variable frequency refrigerator, the compressor is operated at the highest rotation speed when being started, and efficient quick cooling is realized.

step S120: setting a reservation time and a preset temperature;
